We investigated the awareness and acceptability of pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) and potential predicting factors.
This study was conducted among MSM in Beijing, China. Study participants, randomly selected from an MSM cohort, completed a structured questionnaire, and provided their blood samples to test for HIV infection and syphilis. Univariate logistic regression analyses were performed to evaluate the factors associated with willingness to accept (WTA) PrEP. Factors independently associated with willingness to accept were identified by entering variables into stepwise logistic regression analysis.
A total of 152 MSM completed the survey; 11.2% had ever heard of PrEP and 67.8% were willing to accept it. Univariate analysis showed that age, years of education, consistent condom use in the past 6 months, heterosexual behavior in the past 6 months, having ever heard of PrEP and the side effects of antiretroviral drugs, and worry about antiretroviral drugs cost were significantly associated with willingness to accept PrEP. In the multivariate logistic regression model, only consistent condom use in the past 6 months (odds ratio [OR]: 0.31; 95% confidence interval [CI]: 0.13-0.70) and having ever heard of the side effects of antiretroviral drugs (OR: 0.30; 95% CI: 0.14-0.67) were independently associated with willingness to accept PrEP.
The awareness of PrEP in the MSM population was low. Sexual behavioral characteristics and knowledge about ART drugs may have effects on willingness to accept PrEP. Comprehensive prevention strategies should be recommended in the MSM community.
本研究旨在调查男男性行为者(MSM)对暴露前预防(PrEP)的知晓情况和接受意愿,并分析其潜在的预测因素。
本研究在北京的 MSM 中开展。研究对象是从一个 MSM 队列中随机选择的,他们完成了一份结构式问卷,并提供了血液样本,以检测 HIV 感染和梅毒。采用单因素 logistic 回归分析评估与接受意愿相关的因素。将变量逐步纳入 logistic 回归分析,以确定与接受意愿独立相关的因素。
共 152 名 MSM 完成了调查;11.2%的人听说过 PrEP,67.8%的人愿意接受 PrEP。单因素分析显示,年龄、受教育年限、过去 6 个月内坚持使用安全套、过去 6 个月内的异性性行为、听说过 PrEP 和抗逆转录病毒药物的副作用、以及担心抗逆转录病毒药物的费用与接受 PrEP 的意愿显著相关。在多因素 logistic 回归模型中,仅过去 6 个月内坚持使用安全套(比值比 [OR]:0.31;95%置信区间 [CI]:0.13-0.70)和听说过抗逆转录病毒药物的副作用(OR:0.30;95% CI:0.14-0.67)与接受 PrEP 的意愿独立相关。
MSM 人群对 PrEP 的知晓率较低。性行为特征和对 ART 药物的认知可能会影响接受 PrEP 的意愿。应在 MSM 社区中推荐综合预防策略。
